Hair Follicle Drug Testing - Wishram, WA

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a longer-term record of alcohol and other substances by encapsulating biomarkers in the fibers of the hair shaft as it grows. When taken close to the scalp, it can offer a detection timeframe of up to around three months for alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and easy for transport.

A 1.5-inch segment of approximately 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp provides 100mg, the preferred amount for both screening and confirmation purposes. For EtG, additional analyses, and/or evaluations exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for specimen weighing is suggested. If scalp hair is not available, a corresponding quantity of body hair can be used. Head hair specifically indicates scalp hair, while body hair includes all other hair formations (like facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result consist of four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample initially integrates into a lab’s system. This phase covers verifying the correct sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data entry beyond what an electronic chain of custody system provides.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is an economical means to eliminate drug usage for most samples, any positive findings there must be confirmed for courtroom acceptance. Samples showing potential positivity in Screening require further confirmation.

When a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the main sample for the Extraction process. Here, drugs are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluids), underscoring the complexity of performing hair drug screening.

The Confirmation phase for any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives undergo washing if necessary before confirmation. The complete lab activity from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug usage for up to 90 days, whereas urine tests offer a shorter detection period.
• Hard to deceive: It is extremely challenging to bypass a hair drug test, ensuring more precise results.
• Offers historical insights: It enables the tracking of drug use patterns over time, not solely focusing on recent usage.

Limitations:

• Inability to detect recent use: Drugs become visible in hair only after about 5-7 days.
• Expense: Hair drug testing is typically costlier than alternative drug testing techniques.
• Result variability: Variables like hair color and individual growth rates can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the examination targets the hair strand and not the beneath-the-scalp follicle

Why Hair Follicle Testing Beats Urine Testing
